Question

КАТЕР ПРОПЛЫЛ 92 КМ ПО ТЕЧЕНИЮ РЕКИ СКОРОСТЬ ТЕЧЕНИЯ РЕКИ 3 КМ Ч СОБСТВЕННАЯ СКОРОСТЬ КАТЕРА 20 КМ Ч СКОЛЬКО ЧАСОВ ПЛЫЛ КАТЕР

Answer 1

1) 20+3=23 км/ч - скорость катера по течению реки
2) t = S:v = 92:23 = 4 часа
Ответ: 4 часа плыл катер.

Answer 2

Calculation of the Time Taken by the Boat

To calculate the time taken by the boat to travel a distance of 92 km with a river current of 3 km/h and a boat speed of 20 km/h, we can use the formula:

Time = Distance / (Boat Speed + River Current)

Plugging in the given values:

Time = 92 km / (20 km/h + 3 km/h)

Calculating the time:

Time = 92 km / 23 km/h

Time = 4 hours

Therefore, the boat took 4 hours to travel a distance of 92 km with a river current of 3 km/h and a boat speed of 20 km/h.
